hey fiamma, i'm in taralli land here :D...i eat the stuff all the time!

like pavotrouge said, skordalia is basically boiled potatoes, mashed garlic, olive oil(lots) and lemon juice/vinegar all blended together..it takes on a very weird consistency all of a sudden, as you blend it..formes a type of emulsion, a bit like mayonaise. and it's even nice the day after!!
